Optical coherence tomography and indocyanine green angiography findings in acute syphilitic posterior placoid choroidopathy: case report.

The optical coherence tomography (OCT) and indocyanine green angiography (ICGA) findings of a 58-year-old male with acute syphilitic posterior placoid chorioretinitis are reported herein. Best-corrected visual acuity was 20/150 in the right eye (OD) and 20/30 in the left eye (OS) at presentation. On funduscopy, there was a central subretinal placoid yellowish lesion in OD. VDRL and serum FTA-ABS were positive. OCT showed increased reflectance and thickening of the subfoveal RPE-choriocapillaris complex corresponding to the lesion in OD. ICGA revealed a hypofluorescent spot corresponding to the lesion in OD and confluent small dots extending to periphery, without any correspondence in fundus examination. The same dots were also seen in OS, even though no lesions could be observed clinically. Intravenous ceftriaxone 2 g daily was given for 10 days. One month after the first visit, visual acuity improved to 20/30 and marked improvement of the lesion was seen. OCT was normal in both eyes at the final visit.
